Also, to answer your question Mullos..... When any injectors are replaced they should be coded to the computer. The engine will start and run without doing this, but the compensation code is required by the computer and pump to give best performance and economy.
Many shops charge around $150-$200.00 to do this.
If Toyota replace yours, they should do this as part of the job.
Seals.... they are replaced as a matter of course when injectors are replaced, as are o-rings, and fuel line gaskets. TMC also recommends replacing the entire fuel rail. This is not necessary, as long as the work is done by a competent person.
All work needs to be clean, and fuel pipes need to be treated with care.
If you do end up paying for the work, don't bother with getting it done at a TMC dealership. You get nothing extra for it except a decreased bank balance. Any good mechanic can do the work at a fraction of the price..... ie.... all 4 injectors and associated parts as per above, + compensation coding for around $2800-$3000. That is for Denso OE injectors. There are a couple of Chinese factories now making these items, so also be careful there.
Hope this helps.
